Official solo companion app for the P.I. board game, published worldwide by BoardM. In the deduction board game P.I., you become a detective on the hunt for clues: where the crime took place, who did it, and what weapon was used. Deduce all three correctly to solve the case. Choose Your Clues When you select a clue, the app provides a response: Spot Marker: The chosen clue is part of the final answer. Trace Marker: The answer is located in a region adjacent to the clue you pointed to. No Marker: The answer is located further away. Time is Your Score Checking 1 Clue Card: Adds 30 seconds Using a Detective Tile: Adds 50 seconds Incorrect Deduction Attempt: Adds a 100-second penalty Replay the Same Case When a game finishes, you can copy a 10-digit code. Entering this code on any device recreates the exact same case. Share the code with friends to compete under identical conditions! (Note: Games created via code input are not eligible for online ranking registration.) LEADERBOARD 14 locations, 12 suspects, 10 pieces of evidence. That makes 1,680 cases. A new leaderboard starts every month, and you can view this month, last month, or all time. Browsing needs no account. ■ Components Needed Use this app alongside the physical P.I. board game. You will need the game board, Suspect Tiles, Evidence Tiles, and one player color's worth of Trace Markers, Spot Markers, and Detective Tiles. All other components are handled by the app and do not need to be set up. Original board game design: Martin Wallace. P.I. is published by BoardM, which holds the worldwide publishing rights to the game. This is the official companion app, developed and distributed under that authorization. Every illustration, image and text string in the app was created by BoardM.
